SASH-FASTENER.

SE ZECII-ICATIOH forming part of Letters Patent No. 339,324, dated April6, 1886.

Application filed January '2', 1886.

To aZZ whom it may concern.-

Be it known that I, ALLISON MONROE Ros- COE, a citizen of the UnitedStates, residing at Du Bois, in the county of Olearfield and State ofPennsylvania, have invented certain new and useful Improvements inSash-Fastenings; and I do declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beingbad to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

M y invention relates to sash-holders, and particularly to that class inwhich the sashes are adjusted independently of each other, and held inposition by a rod ailixed to one sash passing through a keeper on theother sash.

It consists in combining with the rod hav ingalongitudinal serrated andsmooth portion, a keeper having a corresponding serrated portion toengage the broken or roughened per tion of the rod, a spring to normallykeep the serrations of the rod and keeper out or" con tact, and means toovercome the tension of the spring and bring the parts in contact tohold the sash or sashes in any desired position.

It also consists in novel features, more fully shown and hereinafter setforth and claimed.

In the drawings, Figure l is a front view of a window 1" rame and sashesprovided with my improved holding devices. on the line a: so of Fig. 1.Fig. 3 is a top View of the lower sash, showing the keeper in positionand the rod in section. Fig. 4 is a section on the line y 3 of Fig. 3,with portions of the sash broken away.

The frame A and sashes B and C are of ordinary construction and design,and are simply shown to illustrate the application of my improveddevices.

Depending from the frame is a loop, a, located beyond the plane of thelower sash. A

bar, D, having its upper end bent at right air gles and secured to theupper rail of the sash B, extends downward and passes through a keeper,E, fixed to the upper rail of the sash C. A longitudinal portion, (1, ofthe bar D is is serrated, and the remaining longitudinal portion, d, issmooth.

That portion of the Fig. 2 is a section 4 Serial No. 187,908. (Nomodel.)

keeper adjacent to the serrations d is correspondingly serrated, asshown at e, and is of a width equal to the roughened portion of the bar,leaving a space, 6, opposite the smooth portion of the bar, within whichis located the free end of a spring, F, the other end of the springbeing attached to the base-plate E of the keeper. The distance betweenthe serrated portion 6 of the keeper and its outer wall is sufficient topermit the passage of the bar D, and the free end of the spring F,bearing upon the smooth portion cl, serves to hold the serrated portionof the rod out of contact with the part 6. A set-screw, G, passingthrough the front wall of the keeper, bears upon the rod, and in theoperation of the one sash over the other when raising or lowering forventilation it may be held in the required position by turning thescrew, when the bar will be forced inward against the tension of thespring, and the roughened portions c and d. of the keeper and bar,respectively, will in terlock, thus securing a positive binding betweenthe two sashes. A reverse movement 7 of the setscrew will permit theaction of the spring and a consequent disengagement of the bar andkeeper, as is manifest.

The lower end of the bar has an opening, it, formed therein, to engage ahook, H, on the 30 sash 0. Thus when the upper sash is secured at itshighest position, or nearly so, andthe lower sash is raised, the hook H,engaging the opening, will hold the sash in its elevated position. Thisis an important feature, as it al- 83 ways affords a ready means forholding the lower sash in an adjusted position when the set-screw of thekeeper is not within easy reach. There may be as many of these openingsas desired, and the hook may be located at any convenient position.

A rod, 1, is secured to the bar D in such a manner as to have a partialrotary movement, but fixed relative to an independent longitudina-lmovement. The upper and lower ends of 5 the rod are bent at rightangles, and the upper end is adapted to engage the loop a and hold theupper sash in its highest position. A partial rotary movement of the rodwill disengage its end from the loop and permit the adjustmo ment of thesash. The rod passes through an independent opening, in the keeper.

It will be seen that either sash may be moved over the other. It isevident that the keeper may be attached to the upper sash and the bar tothe lower one Without departing from the spirit of my invention.

It may be found expedient to dispense with the spring, in which case thebar. may be held out of engagement with the keeper by hand whenoperating the sash, or sufficient elasticity may be given to the baritself'to accomplish the same purpose.

The serrated part 6 of the keeper may be integral therewith. or it maybe a separate block or plate inserted therein.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. The combination of a sliding sash, a bar having a longitudinalserrated portion and a longitudinal smooth portion. a keeper havingcorresponding serrated and smooth portions, a spring fastened to thekeeper and bearing on the smooth portion of the bar to keep theserrations of the bar and keeper normally out er being sufficient topermit the disengagement of the serrated parts of the bar and keeper,substantially, as and for the purposes set forth.

3. The combination of the upper and lower sash, a bar secured totheupper sash, a keeper fastened to the'lower sash to engage the bar,and hooks attached to the lower sash to engage perforations in the barwhen the keeper is not in convenient reach, substantially as set forth.In testimony whereof I affix my signature in presence of two witnesses.
